This fitting connects two sections of pipe while allowing future disassembly without cutting the line. The socket weld end connections provide a strong, leak-resistant joint suited for high-purity and corrosive-fluid applications. Plumbers and pipefitters install this union in process, industrial, and commercial piping systems where 316 stainless material is specified for corrosion resistance. The threaded union nut design allows the two halves to be separated and rejoined during maintenance or system modifications.\u003c\/p\u003e\u003cp\u003eThis union is appropriate for use in process piping, chemical handling, food and beverage, marine, and other applications where 316 stainless steel is required to resist chloride and corrosive media. It is suited for both commercial and industrial installations operating within the 150 psi pressure rating. The socket weld configuration is common in smaller-diameter piping systems where a full-penetration weld joint is required by the design specification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e316 stainless steel construction resists corrosion in harsh and chemical-laden environments\u003c\/li\u003e\n\u003cli\u003eSocket weld x socket weld end connections on both halves for strong, full-penetration weld joints\u003c\/li\u003e\n\u003cli\u003e150 psi pressure rating suitable for low-to-moderate pressure service\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch fitting size covers a common mid-range pipe diameter\u003c\/li\u003e\n\u003cli\u003eThreaded union nut allows disassembly and reassembly without cutting pipe\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 1-1\/4 inch socket weld piping systems requiring 316 stainless steel construction and a 150 psi pressure rating.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of socket weld fittings must be performed by a qualified pipefitter or welder in accordance with applicable codes, including ASME B31.3 for process piping. Depressurize, drain, and isolate the affected pipe section completely before beginning work. Socket weld joints require proper gap spacing before welding per applicable welding procedure specifications. Do not exceed the rated pressure of 150 psi in service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Socket Weld x Socket Weld\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded Union Nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.62 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175300\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERIT BRASS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SWM687-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51539251855666,"sku":"SWM687-20","price":92.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eef5205cf23b775658b10f96a8fb4e51.jpg?v=1785837127","url":"https:\/\/voomisupply.com\/products\/merit-brass-swm687-20-pipe-union-1-1-4-in-316-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
